Azure AZ-900 study plan

Draw the Azure resource hierarchy from management group down to resource, labeling where policies and RBAC inherit from

Distinguish regions, region pairs, and availability zones, and justify which to use for three given resilience scenarios

Classify five business scenarios as public, private, or hybrid cloud and state one tradeoff for each

Compile a 25-term architecture glossary written in your own words rather than copied definitions

Compare virtual machines, App Service, Functions, containers, and AKS on control level, scaling model, and billing granularity

Select the best-fit compute service for ten written scenarios and defend each pick in one sentence

Describe how virtual networks, subnets, peering, and DNS work together to connect workloads

Differentiate VPN Gateway, ExpressRoute, service endpoints, and private endpoints by use case and exposure

Map Blob, Files, Queue, and Disk storage to concrete workloads and pick access tiers for three data lifecycle cases

Explain LRS, ZRS, GRS, and RA-GRS redundancy and choose one for four stated durability or latency requirements

Contrast Microsoft Entra ID with traditional Active Directory Domain Services, and separate authentication from authorization with examples

Describe how RBAC role assignments, scope, and Conditional Access combine to control access to a resource

Explain when to create additional subscriptions and how management groups centralize governance across them

Apply tags, resource locks, and Azure Policy to five written compliance scenarios and name the correct mechanism

Identify the cost drivers of a workload and choose between the pricing calculator and the TCO calculator for two stated questions

Set up the concept of budgets and cost alerts by describing what to configure and who to notify

Match fifteen administrative tasks to the right tool among portal, Cloud Shell, Azure CLI, PowerShell, and infrastructure-as-code templates

State three benefits of infrastructure as code and describe what a declarative template does versus an imperative script

Explain what Azure Advisor, Azure Monitor, Log Analytics, and Service Health each answer that the others do not

Describe how alerts and action groups turn a metric or log signal into a notification or automated response

Define cloud computing and contrast consumption-based pricing with capital expenditure using a two-year cost comparison

Differentiate IaaS, PaaS, and SaaS with two concrete Azure examples each and state who manages the OS in each

List the core cloud benefits (high availability, scalability, elasticity, reliability, predictability, security, governance, manageability) and give a one-line example of each

Explain serverless computing and how vertical scaling differs from horizontal scaling

Complete two full-length timed practice exams of about 50 questions in 45 minutes each without pausing

Tag every incorrect answer to a domain and subtopic and rank the gaps by frequency

Re-study only the top three gap areas and re-answer those questions until correct

Condense the whole exam into a single-page recall sheet of numbers, service names, and decision rules

Re-answer every previously missed question until you reach 100% without referencing notes

Take one final timed practice exam and target 85% or higher overall with no domain below 75%

Rehearse exam logistics: test your hardware and network check, confirm acceptable identification, and clear your testing space

Schedule a light review the day before and a full rest block instead of new material
